Three Driving Modes for
Optimum Speed Shift
Driving mode
switch
The three driving modes can be selected
according to job needs and operator's
preference.
L mode:
Starts with the second gear, and makes
gear shift at fast timing. Suitable for
long-distance travel on level ground.
Automatic Transmission with
Load-Sensing System
N mode:
Starts with the second gear and makes
gear shift at slow timing. Suitable for
ordinary digging and loading
operation such as V-shaped load and
carry method.
H mode:
Makes gear shift at timing similar to the
N mode, and automatically shifts down
to the first gear according to loading
conditions without need for shift down
by DSS* or manual shifting.
*Down-Shift Switch
Load increase
Speed increase
Auto shift down when
load increases
Shift up when speed
increases
Optimal speed shift timing is
automatically selected in response to
both travel speed and load.
Smooth Speed Shift by
Electronic Control
Quick, smooth speed shift can automatically be done with less shocks by
electronic control through helical gears.
This allows speedy job-to-job travel with
less soil spills in load-and-carry
operation.
High-Torque Engine and
Capacious Torque Converter
Max. output: 179 kW (240 hp)
Rated output: 163 kW (219 hp)
Max. torque: 1 022 Nm (104 kgf•m)
The new engine yields big torque at a
low speed in direct response to
acceleration without need for full throttle.
The capacious torque converter enables
powerful travel under heavy load, such
as climbing steep or long hills without
losing speed.
Torque Proportional
Differential (Standard)
The torque proportional differential
adjusts driving forces to both wheels.
When road resistances under both
wheels are different, this feature
prevents slippage of a wheel on softer
ground, unlike conventional differentials.
This feature enables the ZW series to get
out of swamps or rough terrain easily.
Limited Slip Differential (Optional)
On snowy roads and rough terrain, the
limited slip differential can work instead
of the torque proportional differential.
This delivers effective driving force to
both wheels for enhanced grip and less
slippage during travel.
An Array of Elaborate Mechanisms for Impressive
Mobility and Big Production
Improved Rise / Run Performance
Arm rising while traveling for improved rise / run performance. On the new ZW Series,
10% higher rise/run performance can be expected, boosting loading efficiency and
increasing productivity.
Smoother Simultaneous Operations with Advanced Hydraulic Circuit
With the new parallel/tandem circuits,
the lift arm and bucket can be operated
at the same time, unlike conventional
machines. This can remarkably increase
digging and loading efficiency for higher
production.
Selectable Clutch Cut-off Timing
S mode
Clutch cut
position switch
N mode
D mode
Clutch cut-off timing can be selected
from three options to suit various job
conditions, including rapid operation on
level ground, and surefooted operation
on gradient.
S mode:
The clutch is cut-off at fast timing by
depressing the pedal for speedy loading
on level ground.
N mode:
The clutch is cut-off by depressing the
pedal midway for surefooted loading on
slope.
D mode:
The clutch is cut-off by depressing the
pedal fully for dumping into a hopper
on slope.
OFF:
The clutch is disabled.
Sophisticated Mechanisms for Higher Job Efficiency
Float System
Lift Arm Kick-Out System
Lift Arm Auto Leveler (Optional)
The float system lets the lift arm follow
up road irregularities by using its selfweight only, without using its hydraulic
circuit. This system is useful in soil-spill
collecting during loading, and snow
plowing.
The lift arm can automatically be raised
up to the preset level. This function is
convenient when loading onto a dump
truck, and when operating at confined
job sites with restricted working height.
The lift arm can automatically be raised
and lowered to the preset level. By using
the switches in the cab, high and low lift
kickouts can be programmed.
Bucket Auto Leveller
The bucket can automatically be levelled
parallel to the ground after rolling the
bucket out. This can eliminate cumbersome bucket repositioning for efficient
loading.
Operator-Friendly Designs for Higher Job Efficiency
Restriction Valve
The restriction valve can effectively
reduce shocks when moving the lift arm
up and down. The bucket does not have
a shockless circuit to allow efficient mud
removal.
Ride Control System
Vibration without Ride
Control
Vibration by Ride Control
by Using Front Weight
The ride control reduces pitching and bouncing during travelling on rough terrain and
snow road by automatic control of the implement. Shocks and vibration can be well
suppressed for riding comfort.
Bi-Level Auto Air Conditioner and
Pressurized Cab
Front / Rear Defrosters
Shock-Dampened Cab
Silicone (Fluid)

comes out from three front air outlets
and two rear outlets to protect
respective windows from fogging,
keeping clear vision even in rain and
cold weather.
Low Noise Design
Hat (Resin Cab Roof)
The hollow hat is provided atop the cab
to form an air space. This greatly helps
reduce the temperature rise in the cab,
and increases the cooling efficiency of
the air conditioner.
The cab rests on fluid-filled elastic
mounts to absorb shocks and vibration,
and reduce resonance.
The cab is well sealed, and the new
low-noise engine is utilized to reduce
sound, along with the following
measures:

Control Unit
In this fuel injection system complying
with the Emission Regulations, one fuel
pump runs to generate high pressure
for distributing fuel to each injector per
cylinder through a common rail.
By electronic control, fuel injection
volume and timing can be precisely
regulated for efficient combustion and
higher horsepower. This also reduces
PM* (diesel plume), fuel consumption
and vibration.
Exhaust
Cylinder Head
The cooled EGR system lets part of
exhaust gasses mix with intake air for
re-combustion to reduce oxygen concentration in the air in the combustion
chamber. This design lowers combustion temperature in the cylinder, reducing fuel consumption and NOx while
yielding more horsepower. This system
also cools down exhaust gas to prevent
incomplete combustion and PM*
emission.
Approximately 95% of the ZW Series can be recycled. The resin parts
are marked to facilitate recycling. The
machine is completely lead-free. The
radiator and oil cooler are made from
aluminum and all wires are lead-less. In
addition, bio-degradable hydraulic oil
is available for jobsites where special
environmental care is required.
*Particulate matter
A Quieter Machine
A number of features make this machine quieter. First, isochronous control of the engine
speed means a restriction of engine speed during no-load and light-duty operation to
suppress sound. A fan with curved blades reduces air resistance and airflow noise.
Third, a time-tested muffler suppresses engine noise significantly and reduces
emissions. This advanced low noise design complies with the 2000 / 14 / EC, Stage II,
directive effective in the European Union from 2006.
Hitachi Silent (HS) Fan
Low Noise Engine
The cylinder block and ladder frame are
strengthened to reduce engine sound.
The HS fan is capable of reducing air
resistance and air flow sound. It is
utilized at the radiator and oil cooler for
quieter operation.
